The CM150RX1‑24A is an Insulated Gate Bipolar Transistor (IGBT) module manufactured by Mitsubishi Electric. It is designed for medium‑to‑high power switching in industrial environments such as motor drives, inverters, UPS systems, and other power electronics requiring efficient, reliable semiconductor switching.

This module is part of Mitsubishi’s CM series, known for combining high voltage capability with good conduction and switching performance.

Electrical Ratings

Notes:

• The module’s 1200 V class rating makes it suitable for systems with DC bus voltages up to ~900 V.

• Low V_CE(sat) reduces conduction losses, improving efficiency.

• Internal Configuration

The CM150RX1‑24A is typically a discrete single IGBT module (i.e., one power transistor with integrated features) intended as a power switching element in a larger converter topology rather than a complete three‑phase bridge.

Key internal elements include:

• Carrier Stored Trench‑Gate Bipolar Transistor (CSTBT™) technology — improves conduction/switching trade‑off.

• Anti‑parallel fast recovery diode — integrated for handling inductive currents in PWM converters.

• Low‑inductance packaging — suitable for high‑speed switching with reduced voltage overshoot.

Unlike multi‑pack “six‑pack” modules, this part serves as a building block for custom converter designs (half‑bridge, full‑bridge, chopper circuits, etc.) with external driver and auxiliary circuits.

Electrical & Switching Characteristics:

• Low on‑state resistance: Typical saturation voltage around 1.7–1.9 V at 150 A helps reduce conduction loss.

• Fast switching response: Advanced IGBT structure for efficient PWM operation with moderate switching speeds.

• Short‑circuit withstand capability: Designed to tolerate brief short‑circuit events until protective circuitry can deactivate the device.

 Typical Applications:

The CM150RX1‑24A IGBT module is used in a variety of power electronics systems, including:

• Motor drives and frequency inverters for industrial AC motors.

• Uninterruptible Power Supplies (UPS) and power conversion systems.

• Welders, induction heaters, and battery chargers where controlled switching is needed.

• DC‑DC converters and chopper circuits in traction and renewable energy systems.
